Legal claims defining the scope of protection, as filed with the USPTO.
1. One or more non-transitory computer-readable media having instructions, stored thereon, that when executed by one or more processors of a user equipment (UE), cause the UE to: obtain, from an evolved Node B (eNB) of a wireless communication network, a time domain averaging indicator having a single bit to indicate that the UE is to restrict interference measurement to a most recent channel state information (CSI)-interference measurement (IM) resource; derive an interference measurement based on the most recent CSI-IM resource in response to the time domain averaging indicator; compute a channel quality indicator (CQI) value based on the derived interference measurement; and report the CQI value to the eNB.
2. The one or more media of claim 1 , wherein the single bit of the time domain averaging indicator is to have a first value to indicate that the UE is to restrict interference measurement to the most recent CSI-IM resource, or a second value to indicate that time domain averaging is unrestricted in a time domain.
3. The one or more media of claim 1 , wherein the time domain averaging indicator is obtained via radio resource control (RRC) signaling.
4. The one or more media of claim 1 , wherein the instructions, when executed, further cause the UE to: receive a channel state information (CSI) feedback model associated with the eNB; and generate CSI for individual sub-bands of a channel based on a determination that the CSI feedback model supports sub-band CQI.
5. The one or more media of claim 1 , wherein the instructions, when executed, further cause the UE to: obtain a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain; wherein the interference measurement is further derived based on the frequency domain averaging window.
6. The one or more media of claim 5 , wherein the frequency domain averaging indicator includes a single bit that is to have a first value to indicate that the frequency domain averaging window includes a single sub-band of a channel or a second value to indicate that the frequency domain averaging window includes all sub-bands of the channel.
7. One or more non-transitory computer-readable media having instructions, stored thereon, that when executed by one or more processors of an evolved Node B (eNB), cause the eNB to: send, to a user equipment (UE) of a wireless communication network, a time domain averaging indicator having a single bit to indicate that the UE is to restrict interference measurement to a most recent channel state information (CSI)-interference measurement (IM) resource; and obtain, from the UE, a channel quality indicator (CQI) having a value based on the most recent CSI-IM resource.
8. The one or more media of claim 7 , wherein the single bit of the time domain averaging indicator is to have a first value to indicate that the UE is to restrict interference measurement to the most recent CSI-IM resource, or a second value to indicate that time domain averaging is unrestricted in a time domain.
9. The one or more media of claim 7 , wherein the time domain averaging indicator is sent via radio resource control (RRC) signaling.
10. The one or more media of claim 7 , wherein the instructions, when executed, further cause the eNB to: send, to the UE, a channel state information (CSI) feedback model associated with the eNB, wherein the CSI feedback model indicates support for sub-band CQI; and obtain, from the UE, CSI for individual sub-bands of a channel based on the indication of support for sub-band CQI.
11. The one or more media of claim 7 , wherein the instructions, when executed, further cause the eNB to: send a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain; wherein the value of the CQI is further based on the frequency domain averaging window.
12. The one or more media of claim 11 , wherein the frequency domain averaging indicator includes a single bit that is to have a first value to indicate that the frequency domain averaging window includes a single sub-band of a channel or a second value to indicate that the frequency domain averaging window includes all sub-bands of the channel.
13. A user equipment (UE) comprising: transceiver circuitry to: communicate with an evolved Node B (eNB) over a channel of a wireless communication network; and receive, from the eNB, a time domain averaging indicator to indicate that the UE is to restrict interference measurement to a most recent channel state information (CSI)-interference measurement (IM) resource; interference measurement circuitry coupled to the transceiver circuitry, the interference measurement circuitry to generate an interference measurement based on the most recent CSI-IM resource in response to the time domain averaging indicator; and feedback circuitry coupled to the interference measurement circuitry, the feedback circuitry to generate CSI associated with the channel based on the interference measurement; wherein the transceiver circuitry is further to transmit the CSI to the eNB.
14. The UE of claim 13 , wherein the time domain averaging indicator has a single bit that is to have a first value to indicate that the UE is to restrict interference measurement to the most recent CSI-IM resource, or a second value to indicate that time domain averaging is unrestricted in a time domain.
15. The UE of claim 13 , wherein the transceiver circuitry is to receive the time domain averaging indicator via radio resource control (RRC) signaling.
16. The UE of claim 13 , wherein the transceiver circuitry is to receive a CSI feedback model associated with the channel, and wherein the feedback circuitry is to generate CSI for individual sub-bands of the channel based on a determination that the CSI feedback model supports sub-band channel quality indicators (CQIs).
17. The UE of claim 13 , wherein the transceiver circuitry is further to receive, from the eNB, a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain; wherein the interference measurement is generated further based on the frequency domain averaging window.
18. The UE of claim 17 , wherein the frequency domain averaging indicator includes a single bit that is to have a first value to indicate that the frequency domain averaging window includes a single sub-band of the channel or a second value to indicate that the frequency domain averaging window includes all sub-bands of the channel.
19. The UE of claim 13 , further comprising: a memory device and a display coupled to the transceiver circuitry.
